Cheveley Park Stud, seeking a sixth win in the race, have two promising contenders in Zonderland (Clive Cox) and Persuasive (John Gosden).

Chris Richardson, managing director of Cheveley Park Stud, said: “Zonderland looks fine. He has wintered well and we are very happy with him.

“I think he will probably go for a Listed race before we consider the Al Shaqab Lockinge Stakes. He ran so well in the Celebration Mile last year that we felt he warranted an entry.

“Similarly, Persuasive looks fantastic and has strengthened well. John Gosden is very happy with her. Both look very nice prospects going forward.The race has been very lucky for us.”

O’Brien has seven of the nine Irish-trained entries, the most of any handler. O’Brien’s septet also features Alice Springs, Cougar Mountain and twice-raced four-year-old De Coronado, who is a brother of the great Zenyatta.
